Technical decisions with rationale:
- Label selection: parallel state to avoid disturbing line logic
- Label list UI: collapsible section in Toolbox with search/filter
- API design: extend DELETE with query params for bulk operations
- Docker: standalone output with multi-stage build
- Theme: CSS variables + Tailwind extension strategy
- Feedback: Toast component with terminal formatting
Includes risk mitigation, migration plan, and testing checklist
Line deletion via Delete tool already exists in current implementation.
Focus on three new capabilities: label-management, docker-deployment, hacker-theme
